ROLLIN H. WHITE, OF CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO THE CLEVELAND TRACTOR COMPANY, OF EUCLID, OHIO, CORPORATION OF OHIO.

TRACK-BELT CALK.

Application filed July 20, 1920. Serial No. 397,784.

To all whom it may concern:

Be it known that I, ROLLIN H. VHITE, a citizen of the United States, residing at Cleveland Heights, in the county of Cuya 5 hoga and State of Ohio,'have invented a certain new and useful Improvement in Track-Bolt Calks, of which the following is a full, clear, and exact description.

The object of the present inventionis to enable one to quickly and easily adapt a track laying tractor for working most advantageously on dilfere 1t kinds of surfaces.

The invention consists of a calk which is so constructed that it may be quickly but l5 securely fastened to the lower'face of the shoe of a track belt link; and the combina tion of this calk with the track belt link substantially as shown in the drawing'and hereinafter described 1 and pointed out #0 definitely in the appended claims.

In the drawing, Fig. 1 is a side elevation of a calk and showingits application to a track belt link. view of the calk. e

A track belt in a track laying tractor is made up of a plurality of pivoted together links. Calks like that which is herein shown are intended to be secured, when necessary, to as many -of the belt links as may be deemed desirable,one calk to each link.

Track belt links to which these calks are adapted are of familiar construction, and include a ground engaging shoe or bottom plate 10, at the front end of. which is a downturned transversely extended grouser rib 12.

Fig. 2 1s a perspective The calk 20 is shaped to fit against the.

lower face of the shoe and the curved rear face of the grouser rib; and it has at .its

front a transverse downwardly extended rib 21 which, when the calk is in place, projects considerably below the 1 wer edge of the grouser rib 12. I l e On the upper face of the calk are two upwardly'extended tapered bosses 22; and

between them a countersunk bolt hole 23.

extending below the rib ,into the openings insaid In the shoe 10 are holes to which the bosses aligned with the hole 23 in 'the calk, when the bosses are in the holes inthe shoe. A

bolt 25 having a heady 24 which fits in the countersunk hole 23, passes through. the

hole in the shoe and a nut 26 is screwed onto this bolt, thereby securely holding the calk to the shoe.

Having described my invention, I claim 1+ 1. In a track belt for track laying tractors, the combination with a track belt link having a bottom plate, said plate being provided with openings and having an end thereof formed with a downwardly extending rib, of a calk having a face which engages with the bottom plate of the link and having an angular projecting portion at one end thereof, the outer surface of the angular surface of the rib on the link, said projection on the link, de-

tachable means for securing the calk tothe link, and means extending fromsaid calks bottom plate to prevent twisting inovement of the calk.

-' 2. Ina track belt for track laying tractors,

the combination with a track belt link having a bottom plateat the end of which is formed a transversely extending rib, of a calk havinga bottom plate of the linkandhaving an angular extensioniwhich engageswith the inner surface of the rib on the link but extends below said rib, the calk being formed with two projections and the link having two openings into which said projections extend and a bolt for fastening the calkto the plate, thereby securing the calk to the plate and preventing relative turning movemcnt.

portion which fits against the In testimony whereof, I hereunto afiix my signature.

ROLLINIH. WHITE.
